@ -35,13 +35,14 @@ The default/standard mode, mode 1, exposes various interfaces.
The UART interface allows one to interact with another device over a UART port, using a USB-CDC device (`/dev/ttyACMx`). Baudrate and other line coding settings are applied from the settings from the USB-CDC host, and thus require no special configuration tool.
It is possible to enable hardware flow control (using `CTS` and `RTS` lines), it can be enabled or disabled using [`dmctl uart-cts-rts`](dmctl#uart-cts-rts).
### JTAG and SWD
The device exposes CMSIS-DAP functionality over a USB HID interface, which can be used for JTAG or SWD debugging. No special configuration is required to use it.
In SWD mode, the pin mapping is entirely as with the standard Picoprobe setup,
as described in Chapter 5 and Appendix A of [Getting Started with Raspberry Pi
Pico](https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf). It has additional SWO support on the TDO/SWO pin.
Pico](https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf). It has additional experimental SWO support on the TDO/SWO pin, but has not been properly tested yet.
In JTAG mode, TCK and TMS have the same pins as SWCLK and SWDIO, respectively,
TDI and TDO are on the next two consecutive free pins.
